Class LongMismatch

java.lang.Object

io.spine.change.LongMismatch

public final class LongMismatch
extends java.lang.Object

Utility class for working with long values in ValueMismatches.

Method Summary

Modifier and Type	Method and Description
static io.spine.change.ValueMismatch	expectedNonZero(long expected, long newValue, int version) Creates ValueMismatch for the case of discovering zero value, when a non zero amount was expected by a command.
static io.spine.change.ValueMismatch	expectedZero(long actual, long newValue, int version) Creates ValueMismatch for the case of discovering not zero value, when a zero amount was expected by a command.
static io.spine.change.ValueMismatch	of(long expected, long actual, long newValue, int version) Creates a new instance of ValueMismatch with the passed values for a long attribute.
static io.spine.change.ValueMismatch	unexpectedValue(long expected, long actual, long newValue, int version) Creates ValueMismatch for the case of discovering a value different than by a command.
static long	unpackActual(io.spine.change.ValueMismatch mismatch) Obtains actual long value from the passed mismatch.
static long	unpackExpected(io.spine.change.ValueMismatch mismatch) Obtains expected long value from the passed mismatch.
static long	unpackNewValue(io.spine.change.ValueMismatch mismatch) Obtains new long value from the passed mismatch.

Method Detail

expectedZero

public static io.spine.change.ValueMismatch expectedZero(long actual,
                                                         long newValue,
                                                         int version)

Creates ValueMismatch for the case of discovering not zero value, when a zero amount was expected by a command.

Parameters:

actual - the value discovered instead of zero

newValue - the new value requested in the command

version - the version of the entity in which the mismatch is discovered

Returns:

new ValueMismatch instance

expectedNonZero

public static io.spine.change.ValueMismatch expectedNonZero(long expected,
                                                            long newValue,
                                                            int version)

Creates ValueMismatch for the case of discovering zero value, when a non zero amount was expected by a command.

Parameters:

expected - the value of the field that the command wanted to clear

newValue - the new value requested in the command

version - the version of the entity in which the mismatch is discovered

Returns:

new ValueMismatch instance

unexpectedValue

public static io.spine.change.ValueMismatch unexpectedValue(long expected,
                                                            long actual,
                                                            long newValue,
                                                            int version)

Creates ValueMismatch for the case of discovering a value different than by a command.

Parameters:

expected - the value expected by the command

actual - the value discovered instead of the expected string

newValue - the new value requested in the command

version - the version of the entity in which the mismatch is discovered

Returns:

new ValueMismatch instance

of

public static io.spine.change.ValueMismatch of(long expected,
                                               long actual,
                                               long newValue,
                                               int version)

Creates a new instance of ValueMismatch with the passed values for a long attribute.

unpackExpected

public static long unpackExpected(io.spine.change.ValueMismatch mismatch)

Obtains expected long value from the passed mismatch.

Throws:

java.lang.RuntimeException - if the passed instance represent a mismatch of non-long values

unpackActual

public static long unpackActual(io.spine.change.ValueMismatch mismatch)

Obtains actual long value from the passed mismatch.

Throws:

java.lang.RuntimeException - if the passed instance represent a mismatch of non-long values

unpackNewValue

public static long unpackNewValue(io.spine.change.ValueMismatch mismatch)

Obtains new long value from the passed mismatch.

Throws:

java.lang.RuntimeException - if the passed instance represent a mismatch of non-long values
